What is Energy

Energy is Defined as the ability to produce change and do

• light

• work

• heat

• sound

There are two categories of energy

• solid and liquid

• potential and kinetic

• nuclear and thermal

Stored energy and energy of position (gravity) is what form of energy

• potential

• kinetic

Chemical Energy is an example of

• kinetic

• potential

Energy of motion - motion of waves, electrons, atoms, molecules, substances and object

• potential energy

• kinetic energy

Thermal energy is an example of

• potential energy

• kinetic energy

When we use energy, we do not use it completely, we change its

• amount

• form

• sound

Renewable energy sources are

• limited

• replenished in a short period of time

Renewable energy examples include...

• coal and wind

• geothermal and wind

• wind and coal

• natural gas and geothermal

Nonrenewable energy sources are

• limited

• replenished in a short period of time
